STATIONARY FIRE-EXTINGUISHER SYSTEM.

Specification of Letters Patent.

Application filed September 5,1914. Serial No. 860,446.

To all'wkom it may concern Be it'known that I, Ronnnr L. CooNnY, a citizen of the United States, residing at At lanta, in-the county of Fulton and State of Georgia, have invented new and useful Im provements in Stationary Fire-Extinguisher Systems, of which the following is a specification. a This invention relates to improvements in stationary fire extinguisher systems, proposing a system of the pressure controlled type and its objects are to provide a system of simple structural character and Which shall be rapid, certain and reliable in its operation.

An embodiment of the invention is illustrated in the accompanying drawings, the

in which Is arranged an invertible acid bottion of the acid bottle may with convenience be of the construction shown in my prior U. S. Patent, No. 1,075,195 of Oct. 7 ,v 1913,-

and includes a vertical latch 3 formed to engage an arm 1 carried by the acid bottle and slidably mounted in a gland 5 fitted in the wall of the tank 1. The system includes the usual distributing pipe 6 leading from the tank and beyond the tank connect-ed to the riser '7 which supplies the leaders or laterals 8, these having at suitable intervals the usual sprinkler heads or distributing valves 9.

According relatively small vessel or cup 10 is arranged at the upper end of the riser, communicating therewith and a-float 11 is arranged in this vessel, the float being supported by a body of non-freezing liquid 12 which fills the vessel 10, the riser 7 and the leaders or laterals 8. The float 11 controls the operation of the system and in the example shown is connected by a cord or wire 13, trained over suitably arranged sheaves 14, to the latch 3. A frangible imperforate diaphragm 15, preferably composed of membrains of "sufiicient strength to resist the to the present invention, a

weight of the column of liquid in the riser 7 is interposed at a suitable point in the riser or in the distributing pipe and at an elevation below that of the lowermost leader 8. A check valve 16 is arranged in the riser 7 below the vessel 10 and at an elevation above that of the uppermost leader 8.

When a sprinkler head or distributing valve is opened at the time of a fire, the non-freezing liquid in the piping of the system escapes and during its escape the float 11 descends in the cup 10, and, functioning as a weight, lifts the latch 3 from engagement with the acid bottle, which, as

usual, being mounted off-center discharges its acid into the tank to mix with the alkaline solution therein. The developed high pressure causes the breakage of, the diaphragm 15 and the extinguishin solution flows past the now open diap ragm into the piping system, escaping through the open sprinkler head or distributing valve. The check valve 16 is arranged to prevent the extinguishing solution from flowing to the vessel of cup 10.

Having thus fully described my invention, I claim:

1. A chemical mixing fire extinguisher system including a tank, an invertible acid bottle arranged therein, a movable controlling element for the acid bottle, a distributing pipe leading from the tank, a vertical pipe connected to and extending upwardly from said distributing pipe and having valved normally closed leaders or laterals, a vessel fitted upon the upper end of said vertical pipe, the vessel and the vertical pipe together with its leaders or laterals containing a non-freezing liquid, a float arranged Within the vessel, and a cord connecting the float, and the controlling element externally of the vertical pipe and operative to move the controlling element upon the descent of the float.

2. A fire extinguisher system including fire extinguisher agent supply means having a movable controlling element, a distributing pipe leading from said supply means, a vertical pipeconnected to and exupper end of the vertical pipe, the vessel and the vertical pipe together with its lead- In testimony whereof I have hereunto set ers or laterals containing a non-freezing my hand in presence of two subscribing wit- .liquid, a float arranged within the vessel, nesses.
